- invention rel-ates to field implements;

and more particularly to a machine for dc straying weeds, grass and analogous growth, tending to hinder the cultivation'o'f straw;

The machine is mounted 'upon'Wheel's and is constructed to operate between adjacent r'owsof plants and is stabilizedby'a Wheel disposed to run in the space paralleling the space in which. the grass and Weeds are long tudinal or side bars 1 which are offset at their front ends, as indicated at 2, and

ends. A platform 4 is mounted upon the main frame and secured thereto in any determinate Way. Thills 5 are secured to the '7 il 7 ofiset portions 2 of the main frame and pro destroyed; The mainframe includes 7 7 "side members 16. .A c'ross bar12'6 'formsiaf wtie-and connects the upwardly bent end p orconnected by means of a transverse bar 3 which is forwardly curved intermediate its videconvenient means-for hitching a horse to the machine fordrawing it over thefield when in service; An axlej 6 is mounted. in the main frame and projectslaterally theiefrom and receive's'wheelsfi and brace" 9'supportsthe outer end of'the axle Z6 and is bolted or otherwise secured to aj'si'de barof'th'einain-fram'e. The brace 9 is 'substa tially of v-formand is strengthened;

means of astay 10., The wheel 8constitut es a driver for-operating the cutting mecha ni'sm. A transverseshaft lllparallels'the axle and isfc'onne'cted to the Wheel8to be I operated thereby. 'A sprocket wheel} '12 if'otatable with the groundwhee'l 8,i s conne'cted by means of aflsp'roeket chain I3 to a sprocket Wheel let fast to the shaft 11. "Power is taken from the shaft 11 to operate the rotarycutter 15 which destroys the grass and 'Weedswhen' the machine islin operation.

Therotary' "cutter 15 is mounted int frame which includes similaror like side member's'16 which are pivoted intermediate their ends to the main frame 11617.: Each-hf the members 16 comprises an upright Sand v a forwardlyand dow wardly eurv'edzpor-- tion 19f [A transverse rod 20' connects the upper ends ofthe elements 1'8.- Ii' lever 21 pivoted at its lower end to the platfonne; extends withinf convenient reach of v the drivers seat'22 andis provided-With the usual hand latch for cooperation Witha' toothed segment 23 whereby the lever is held in then'equired adjustedposition. A- r'od 24: connects thelever el'with'the transverse rod 20, Movement of the lever 2-1 efi'ects' a pivotal movement of the frame tfcomprisjing the member's'l6 and a corresponding VQI tical' "adjustment of the cutting mechanis'in carried therebyf A, blade 25 has its" end portions-bent and securedto the lower for- Ward ends'of the curved porti'oi'is 19' of the tions of the blade 25; j'It' will jthus be un der'stood that pivotal movement -01 the frame cdm fisingthe side members 16 effects" a vertical adjustment ofthe cutting mechaplates 27 fast to the ends of the shaft 26,

and cutters 28 which curve outwardly between their ends. The terminal portions of thecutters 28 are secured to the plates 27.

The curved or bulged outline of the cutters;

28 results in the provision of a rotary cutter which is of maximum diameter at a middle point and which tapers toward opposite ends, as indicated most clearly'in Figure 2 of the drawings. r The blade curves in conformity to the curvature of the cutters 28 with which it coacts to destroy the grass and weeds A when the machine is in action.

A casteriwheel 32 supports the rear portion of the machine and is in line with the ground wheel 8.

The machine is of such proportions as to admlt' of the cutting mechanism operating in the space formed between adjacent rows of'plants. The wheels 8 and 32 travel in the center of the space from which the weeds and grass are removed. The wheel 7 travels midway of the space adjacent and paralleling the space actedupon by the machine for exterminating the objectionable growth to be destroyed. It will thus be understood that the wheel 7 operates to stabilize the machine in its travel'over thefield, one row of the plants beinfl disposed between the wheel 7 at one side and the wheels 8 and 32 at the opposite side.

Having thus described the invention,

' what is claimed is:

'1. A .weed cutter comprising ,a' main framev including side bars having laterally extending portions offset at their forward ends, a supplemental frame pivoted to the main frame at the rear of and extending across the laterally extending portions, a cutting mechanism mounted upon the supplemental frame and disposed in advance of the laterally extending portions of the main frame, and means mounted upon the main frame for pivotally adjusting the supplemental frame whereby to vertically adjust the cutting mechanism.

2. A weed cutter comprising a main frame, a supplemental frame including similar side members pivoted intermediate their ends to the main frame and comprising a rear upright portion and a forwardly and downwardly curved portion, 'means connecting the upright portions of the side members, a relatively stationary blade hav-v side members, a rotary cutter mounted upon the pivoted frame at the ends of the stationary blade and bowed outwardly from end to end to coact with said blade, and means mounted upon the main frame for pivotally adjusting the frame carrying the cutting mechanism whereby to adjust the latter vertically.

3. A weed cutter comprising a main frame, an axle mounted upon the main frame and projecting laterally therefrom forsome distance, wheels at opposite ends of the axle, the one" constituting a driver and the other a stabilizer, a caster wheel at the rear of the main frame inline with the drive wheel, a rotary cutter at the front end of the main frame, and connecting means between said rotary cutter and the drive wheeh v A. A weed cutter comprising a main frame including side bars which are laterally offset at their forwad ends and connected by means of a cross bar, a suppleopposite end portionsof the axle, the one constituting a driver and the other a stabilizer, connecting means between the drive wheel and the rotary cutter, and a caster wheel at the reanof the main frame substantially in linewith the drive wheel.

: 5. A rotary weed cutter comprising a plurality of blades bowed outwardly between their ends and connected at their ends to rotate about a common axis. v 6. VA cutting mechanism comprising a relatively stationary blade'bowed from endto end, and a bowed cutter mountedat its ends for rotation aboutan axis passing through the ends of the relatively stationary blade. In testimony whereof Iaffix my signature.
